Overview of NC errors TwinCAT 12 Version: 1.1 Error(Hex) Error(Dec) Error type Description 4210 16912 Address "Encoder address" An axis in the group does not have an encoder, or the encoder address has not been initialized. 4211 16913 Address "Controller address" An axis in the group does not have a controller, or the controller address has not been initialized. 4212 16914 Address "Drive address" An axis in the group does not have a drive, or the drive address has not been initialized.
4213 16915 Address "GROUPERR ADDR MASTERGENERATOR" _ _ 4214 16916 Address "Axis interface NC to PLC address" Group/axis does not have an axis interface from the NC to the PLC, or the axis interface address has not been initialized. 4215 16917 Address "Slave axis address" An existing master/slave coupling is to be removed from the group, but there is no valid address for the slave axis. 4216 16918 Address "Table address unknown" The table, respectively the table ID, is unknown. This table is used for the master/slave coupling or for the characteristic curve. 4217 16919 Address "NcControl address" The NcControl address has not been initialized.
4218 16920 Initialization "Axis is blocked for commands while persistent NC data are queued" Axis is blocked for commands while waiting for valid IO data to accept the queued persistent NC data. 4219 16921 Function "The scaling mode MASTER-AUTOOFFSET is invalid because no reference table was found". The used scaling mode MASTER-AUTOOFFSET is invalid in this context because an existing reference table is missing. This error can occur for example when adding cam tables without a unique reference to an existing cam table.
421A 16922 Parameter "The master axis start position does not permit synchronization" When a slave axis is being coupled on, the position of the master axis does not permit synchronization at the given synchronization positions. 421B 16923 Parameter "Slave coupling factor (gearing factor) of 0.0 is not allowed" A master/slave coupling with a gearing factor of 0.0 is being created. This value is not allowed, since it does not correspond to any possible coupling, and division will generate an FPU exception. 421C 16924 Function "Insertion of master axis into group not allowed" A master axis is to be inserted into a group at a location that is already occupied by another master axis.
Maybe the reconfiguration cannot be done, because this axis has got an existing slave coupling. This master/slave coupling must be revoked before. 421D 16925 Function "Deletion of master axis from group not allowed" (INTERNAL ERROR) A master axis is to be removed from a location in a group that is not in fact occupied by master axis. 421E 16926 Function "Function/feature is not supported from the setpoint generator A function or feature is not supported from the setpoint generator (e.g. PTP master setpoint generator). This can be in general or only in a special situation. 421F 16927 Initialization "Group initialization" Group has not been initialized.
Although the group has been created, the rest of the initialization has not been performed (1. Initialization of group I/O, 2. Initialization of group, 3. Reset group).
